Green city

Posted on Friday, June 16th, 2006.

We have heard many stories about how dirty Pittsburgh used to be when the steel industry dominated the area’s economy and life. It’s vegetation was quite barren we were told. Today universities, biomedical technology, health care, tourism, finance, and services have become the city’s major employers… and vegetation, most notably trees, have grown back! Pittsburghers passing by our booth and the Carnegie Library seem to enjoy the Mulberry tree planted right behind it.
